Molecular Geometry

Front

What is molecular geometry?

Back

Molecular geometry refers to the three-dimensional arrangement of atoms within a molecule.

Front

What theory is commonly used to predict molecular shapes?

Back

The VSEPR (Valence Shell Electron Pair Repulsion) Theory is used to predict molecular shapes based on the repulsion between electron pairs.

Front

What is the shape of a molecule with four bonding pairs and no lone pairs?

Back

Tetrahedral.

Front

What is the shape of a molecule with two bonding pairs and two lone pairs?

Back

Bent.

Front

What is the shape of a molecule with five bonding pairs?

Back

Trigonal bipyramidal.

Front

What is the shape of a molecule with six bonding pairs?

Back

Octahedral.

Front

How does a Lewis Structure help in determining molecular shape?

Back

A Lewis Structure shows the arrangement of electrons and bonds, which helps in visualizing the molecular geometry.

Front

What is the bond angle in a tetrahedral molecule?

Back

Approximately 109.5 degrees.

Front

What is the bond angle in a trigonal planar molecule?

Back

Approximately 120 degrees.

Front

What is the bond angle in a trigonal bipyramidal molecule?

Back

90 degrees and 120 degrees.
